Description
Technical field
This method that the dyeing extract that relates to plant self is used on textiles is specifically related to dye on the Suaeda salsa natural dye method of cellulose base fiber fabric.
Background technology
In recent years, because the influence of environmental problem and energy problem, people are tending towards pursuing continuable, and are eco-friendly and the human health advantageous method produced dyestuff.The exploitation natural dye is the general trend that the world uses the dyestuff development, natural dye is meant and obtains from plant, animal or mineral resources, seldom or not pass through the dyestuff of chemical process, a lot of natural dyes have safe and reliable, the tone nature, near advantages such as natural materials, natural, multi-functional is the trend of dyestuff development.
Alkali paulin (Suaeda salsa) saline land, tender seedling claims " wolf tail bar ", often is called " HAIYINGCAI ", " alkali wormwood artemisia ", " salt wormwood artemisia ", annual herb, stem is upright, cylindrical, up to 30~100 centimetres, Hua Dansheng or 2~3 have handle to cluster on the short handle of axil, the group's of being umbrella, perianth is the five-pointed star shape in the fruit phase, and normally March in time, early and middle ten days all can be emerged to early June, and epigeal cotyledon is scarlet.Be the florescence 7~August, and be productive phase 9~October, November the initial seed full maturity.Plant is red as fire when ripe, has ornamental value.Be typical halophytes, its cultivation technique is more extensive, mainly is distributed in northeast, northwest, North China and Henan, Shandong, Jiangsu, zhejiang and other places.The fluffy commodity of alkali is good, and the fluffy plant type of alkali is attractive in appearance, and the refined title of " emerald coral " is arranged; Fresh and tender cauline leaf is nutritious, has special seafood flavor, and mouthfeel is good.Cure mainly dyspepsia stagnation, heating etc. and cut to be used as medicine.Be a kind of fabulous wild plant resource of doing feed, medicine, food etc., containing huge ecology, economic and social benefit.
Ripe saline land alkali paulin stem, leaf take on a red color, and are rich in a large amount of natural colouring matters.Publication number is that CN101204217A and publication number are that the patent of CN101747663A was carried out research and report to extraction method of natural pigments in the alkali paulin saline land, and the pigment of extraction mainly is used in food service industry with the form of food coloring.Up to the present, the research that fabric dyes is not appeared in the newspapers as natural dye with the Suaeda salsa extract.
Summary of the invention
Technical problem to be solved by this invention provides the method for a kind of Suaeda salsa natural dye to cellulose base fiber fabric, and this method utilization has the direct dyeing of textile dyeing equipment now, does not increase equipment, does not increase cost; Cellulose base fiber fabric lovely luster through the present invention's dyeing has good washing fastness and fastness to rubbing, is suitable for suitability for industrialized production, and is nontoxic, harmless, pollution-free, has a good application prospect.
The method of dying cellulose base fiber fabric on the Suaeda salsa natural dye of the present invention comprises:
The Suaeda salsa extract (is gathered stem, the leaf of ripe Suaeda salsa, pulverizing the back drops in the water, the pH value is 5,50 ℃ of following lixiviates were filtered after 20 minutes, with the filtrate concentrate drying of collecting, obtain the dyestuff pulvis, during dyeing pulvis be made into certain density dye liquor) as dyestuff, the cellulose base fiber fabric after cation-modified is carried out direct dyeing.
Detailed process is:
1, the modified technique of cellulose base fiber fabric
The modification of cellulose base fiber fabric: cellulose base fiber fabric is put into modifier solution by cation modifier 4~8% (o.w.f) and 4~6g/LNaOH by 1: 50 bath raio, at room temperature the programming rate with 2 ℃/min is warmed up to 70~90 ℃, reaction 10~20min.
The modification post processing: hot water wash (40~50 ℃, 10min) → cold wash → pickling (2g/L HAc, 2min) → cold wash → oven dry.
2, dyeing
Compound concentration is 40~60 ℃ of Suaeda salsa natural dye dye liquor, the dyeing temperature of 10~20% (o.w.f), and bath raio is 1: 20~50, dye liquor pH value 3~6, and dyeing time 30~60 minutes dyes completely, takes out fabric washing, and (Na soaps
2C0
3Concentration 1g/L, neutral soap 2g/L, bath raio 1: 50,40~50 ℃ of temperature, the time 15~25min), washing is dried in the shade.
Wherein said o.w.f: heavy to fabric.
Wherein said bath raio: the ratio of fabric quality and solution quality.
Wherein said cation modifier is: any in the epoxies cation modifier, and as 2,3-glycidyl trimethyl ammonium chloride.
Wherein said cellulose base fiber fabric material is: one or more blending in cotton, flax, ramie, sisal hemp, bamboo fibre, day silk, model, the viscose glue.
By chemical bond or physical absorption cationic compound is handled on the cellulose fibre, on fiber, introduced cation group, can improve the affinity of Suaeda salsa natural dye, improve the dye-uptake of Suaeda salsa natural dye cellulose fibre to cellulose fibre.
According to GB/T 3921.1-1997 textile color stability test color fastness to washing; Fabric COLOR FASTNESS test analysis is carried out in the evaluation of GB/T 3920-1997 textile color stability test fastness to rubbing.The colour fastness to rubbing of fabric and color fastness to water all reached and take requirement after result's demonstration was dyed.
Beneficial effect:
(1) the existing textile dyeing equipment direct dyeing of the inventive method utilization does not increase equipment, does not increase cost, is applied to the cleaner production of textile industry, can produce in a large number.
(2) dyeing of the present invention is simple, dyes that back textile dyeing fastness is good, colour-fast, nondiscolouring, favorable reproducibility; Color and luster is natural, graceful.
(3) the inventive method does not exist synthetic dyestuffs to the pollution of environment with to the injury of human body; Can obtain ecology, safe, nontoxic natural dye dying fabric, have suitability for industrialized production and Application Prospect.
(4) saline land the alkali paulin can improve ecological environments such as salt-soda soil, beach ground positive role is arranged, and at feed, medicine, field of food multipurpose is arranged in addition, easily enlarges plantation, can realize large-scale planting.
